توقفت عن التفكير كمبرمج في تلك المرحلة وعدت إلى التفكير كفيزيائي. لقد أذهلني كيف يمكننا محاكاة الظواهر الفيزيائية ببضعة أسطر من التعليمات البرمجية.

These lines portray a tale of creation and vanishing. It describes the creation of a photon, its subsequent disappearance when an electron absorbs it on the cathode plate’s surface, the subsequent departure of the electron from the cathode, and lastly the eventual disappearance of the electron when it reaches the other plate and captured.

The paper: Using a web-based and stand-alone oscilloscope for physics experiment during Covid-19 pandemic, Mahizah Ismail et al (2023), Phys. Educ. 58 015006, is based on the Virtual Oscilloscope simulation. This paper was authored by Mahizah Ismail, Farid Minawi, Wan Zul Adli Wan Mokhtar, Noraihan L Abdul Rashid and Ahmad K Ariffin.

Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.

The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).

If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with remainder. Another application on long division with float quotient is also available in the simulations section.

With this rich simulation, you can visualize and measure the phase difference between two sound waves using two microphones connected to an oscilloscope. Moreover, you can determine the speed of sound in air by measuring the distance between the two microphones when their waveforms are in phase, taking into account the frequency of the sound wave that is controlled by the sine wave generator.

With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.

With this comprehensive and realistic-like photoelectric effect experiment simulation, you will be able to illustrate the following:

The variations of the photocurrent versus potential.

The variations of the photocurrent versus light intensity.

The variation of the kinetic energy of the ejected electrons versus the incident light frequency.

It comes with a graph where you can trace each type of variation as you vary the parameters of the experiment.

Plus, you can experiment and discover more with this simulation.

Using this simulation, you can demonstrate the conservation laws in a one-dimensional elastic collision (The law of conservation of linear momentum and the law of conservation of kinetic energy).
